5.2. VEHICLE ACCESS IN LOGIC “A”
In the configuration for the management of a lane in logic “A” you
need to add a detector FG1. Fasten the DIN guide on the two
available screws and press the detector in place.
Prepare a 24 Vdc power supply and perform the connections as
shown in fig.13.
Presence Time and Reset
The presence time can be set
using the
microswitch
“
h
”. At the end of the
presence time the detector
signals “loop free” and self-calibrates. The presence time starts
when the loop is engaged. An automatic reset is performed
when the detector is activated or when the dip
“
h
” setting changes.
Operation of the Relay
The detector is equipped with 2 relays:
Relay 1 supplies a presence
contact, while Relay 2 sends a pulse
when the loop is disengaged. The operation of
Relay 1 can be selected by changing the setting of the
dip “
r
”.
N.B.: For this application you need to select the operation
“N.O.” contact.
Frequency selection
The detector operating frequency
can be set on
two levels according to the position
of the loop connector.
Frequency depends furthermore
on the loop shape, on the
number of windings and on the cable total length.
N.B.: For any further explanations on the operation of the
detector FG1, please refer to the specific instructions of
the product.
5.3. VEHICLE ACCESS IN LOGIC “P”
In the configuration for the management of a lane in logic “P”
you need to add the detector FG2. Fasten the DIN guide on the
two available screws and press the detector base in place.
fig.13:
the token insertion slot only opens when a vehicle is on the
magnetic loop. The gate or beam opening command must be
connected to the microswitch of the accepting module (see
Chapter. 5.1.).
For the detector FG1 programming, operate as follows:
Sensitivity
The detector sensitivity can
be set on four
different levels using the two first
microswitches on top
(close to letter
s
).
